Forget about passing notes in study hall; some teens are now using their cell phones to flirt and send nude pictures of themselves.
Regulators are debating the risks and benefits of research that implants stem cells in humans.
Can a state do what a country cannot, and transform the way stem-cell research is funded? Erika Check Hayden reports on the California Institute for Regenerative Medicine.
Just as fire engines arrive quickly at the scene to save people and property, the cells that fight viruses have to reach the site of an infection promptly to mount a protective response...

Scientists have for the first time identified stem cells that allow the pituitary glands of mice to grow even after birth. They found that, in contrast to most adult stem cells, these cells are distinct from those that fuel the initial growth ...
